Use of Proceeds

The Company intends to use the net proceeds from the Convertible Notes Offering primarily for working capital and general corporate purposes, and has not allocated specific amounts for any specific purposes.

2024 First Notes

The 2024 First Notes become due and payable on September 30, 2024 (the “Maturity Date”) and may be prepaid provided that an Event of Default (as defined therein) has not occurred. The 2024 First Notes bear interest on the unpaid principal balance at a rate equal to 10% (computed on the basis of the actual number of days elapsed in a 360-day year) per annum accruing from the Eighth Closing Date until the 2024 First Notes become due and payable at maturity or upon their conversion, acceleration or by prepayment, and may become due and payable upon the occurrence of an Event of Default under the 2024 First Notes. Any amount of principal or interest on the 2024 First Notes which is not paid when due shall bear interest at the rate of the lesser of (i) 18% per annum or (ii) the maximum amount allowed by law from the due date thereof until payment in full (the “Default Interest”).

The 2024 First Notes issued in connection with the Eighth Closing are convertible into an aggregate of 259,200 shares of Common Stock (such shares of Common Stock, the “Conversion Shares”) at the option of the holder of the 2024 First Notes (the “Holders”) from the Eighth Closing Date at the Conversion Price (as defined below) through the later of (i) the Maturity Date and (ii) the date of payment of the Default Amount (as defined in the 2024 First Notes); provided, however, the 2024 First Notes include a provision preventing such conversion if, as a result, the Holder, together with its affiliates and any other persons whose beneficial ownership of Company Common Stock would be aggregated with the Holder’s, would be deemed to beneficially own more than 4.99% of the outstanding shares of the Company’s Common Stock (the “Note Ownership Limitation”) immediately after giving effect to the Conversion; and provided further, the Holder, upon notice to the Company, may increase or decrease the Note Ownership Limitation; provided that (i) the Note Ownership Limitation may only be increased to a maximum of 9.99% of the outstanding shares of the Company’s Common Stock; and (ii) any increase in the Note Ownership Limitation will not become effective until the 61st day after delivery of such waiver notice. As previously disclosed in the Current Report on Form 8-K filed by the Company on September 19, 2024, effective September 15, 2024, among other things, the principal amount the Notes issued in connection with the Fourth Closing, Fifth Closing, Sixth Closing and Seventh Closing, was increased by a factor of 1.03. Giving effect to the foregoing, the 2024 First Notes issued in connection with the First Closing, Second Closing, Third Closing, Fourth Closing, Fifth Closing, Sixth Closing, Seventh Closing and Eighth Closing have a total outstanding principal amount of $3,148,608, and are convertible into an aggregate of 6,297,216 shares of Common Stock.

The initial conversion price of the 2024 First Notes (the “Conversion Price”) shall be equal to $0.50 per share and may be reduced or increased proportionately as a result of any stock dividends, recapitalizations, reorganizations, and similar transactions. If the Company fails to deliver the shares of Common Stock issuable upon a conversion by the Deadline (as defined in the 2024 First Notes), then the Company is obligated to pay such 2024 First Note Holders $5,000 per day in cash for each day beyond the Deadline.

The 2024 First Notes contains customary events of default, which includes, among other things, (i) the Company’s failure to pay when due any principal or interest payment under the 2024 First Notes; (ii) the insolvency of the Company; (iii) delisting of the Company’s Common Stock; (iv) the Company’s breach of any material covenant or other material term or condition under the 2024 First Notes; and (v) the Company’s breach of any representations or warranties under the 2024 First Notes which cannot be cured within five days. Further, Events of Default under the 2024 First Notes also include (i) the unavailability of Rule 144 on or after six months from the Issue Date (as defined therein); (ii) the Company’s failure to deliver the shares of Common Stock to the 2024 First Note Holders upon exercise by such Holder of its conversion rights under the 2024 First Notes; (iii) the Company’s loss of the “bid” price for its Common Stock and/or a market and such loss is not cured during the specified cure periods; and (iv) the Company’s failure to complete an uplist to a National Exchange (as defined therein) by September 30, 2024.

Upon an Event of Default, the 2024 First Notes shall become immediately due and payable and the Company shall pay the 2024 First Note Holders an amount equal to 125% (the “Default Premium”) multiplied by the sum of the outstanding principal amount of the 2024 First Notes plus any accrued and unpaid interest on the unpaid principal amount of the 2024 First Notes to the date of payment, plus any Default Interest and any other amounts owed to the Holder under the SPA (the “Default Amount”); provided that, upon any subsequent Event of Default not in connection with the first Event of Default, the Holder shall be entitled to an additional 5% to the Default Premium for each subsequent Event of Default. At the election of each 2024 First Note Holder, the Default Amount may be paid in cash or shares of Common Stock equal to the Default Amount divided by the Conversion Price at the time of payment.

Upon the closing of the transaction that results in the uplist of the Common Stock to a National Exchange, 100% of the then outstanding principal amount of the 2024 First Notes shall automatically convert (the “Automatic Conversion”) into shares of Common Stock (the “Automatic Conversion Shares”), with the conversion price for purposes of such Automatic Conversion being $0.515625 per share. Upon the Automatic Conversion and to the extent that the beneficial ownership of the Holders of 2024 First Notes would increase over the applicable Note Ownership Limitation, the Holder will receive pre-funded warrants (the “2024 Note Conversion Pre-Funded Warrants”, and the shares issuable upon exercise thereof, the “2024 Note Conversion Pre-Funded Warrant Shares”) in lieu of shares of Common Stock otherwise issuable to the Holder in connection with the Automatic Conversion, which 2024 Note Conversion Pre-Funded Warrants shall have an exercise price of $0.000125 per share, may be exercised on a cashless basis, shall be exercisable immediately upon issuance and shall contain a customary beneficial ownership limitation provision. In addition, upon the Automatic Conversion, the Holder shall receive a warrant (the “Uplist Conversion Warrant”, and the shares issuable upon exercise thereof, the “Uplist Conversion Warrant Shares”) to purchase a number of shares of Common Stock equal to the number of shares of Common Stock (or shares of Common Stock underlying 2024 Note Conversion Pre-Funded Warrants, if any) issued upon the Automatic Conversion. The Uplist Conversion Warrant shall have an exercise price per share of $0.50 and shall otherwise be identical to the warrants (other than pre-funded warrants) sold pursuant to the securities purchase agreement dated November 8, 2023, as amended. The Company also agreed in the 2024 First Notes to file no later than 60 days after the closing of an uplist to a National Exchange a registration statement on Form S-4, or other appropriate form, registering the offer by the Company to exchange, on a one-for-one basis, all outstanding Uplist Conversion Warrants and certain other warrants for newly issued warrants identical to the warrants being sold in the offering that results in the uplist to a National Exchange, which warrants are expected to be listed under the symbol “ARTHW.”

The 2024 First Notes issued in connection with the Fourth Closing, Fifth Closing, Sixth Closing, Seventh Closing and Eighth Closing will be senior in priority to the 2024 First Notes previously issued in connection with the First Closing, Second Closing, and Third Closing, and the notes previously issued pursuant to the Securities Purchase Agreement, dated as of July 6, 2022, by and among the Company and each of the parties listed on the signature pages thereto.

Registration Rights Agreement

On the Initial Closing Date, the Company entered into a Registration Rights Agreement with the Investors (the “Registration Rights Agreement”), pursuant to which the Company is obligated, subject to certain conditions, to file with the Securities and Exchange Commission within 60 days after the Initial Closing Date one or more registration statements (any such registration statement, a “Resale Registration Statement”) to register the Conversion Shares for resale under the Securities Act of 1933, as amended (the “Securities Act”). The Company’s failure to satisfy certain filing and effectiveness deadlines with respect to a Resale Registration Statement and certain other requirements set forth in the Registration Rights Agreement may subject the Company to payment of monetary penalties.

Security Agreement

In connection with the issuance of the 2024 First Notes, the Company entered into a Security Agreement with the Collateral Agent (as defined therein) on behalf of the Investors on the Initial Closing Date (the “Security Agreement”), pursuant to which the Company and each of its subsidiaries (together with any persons who execute a joinder to the Security Agreement, the “Debtors”) provided as collateral to the Investors a security interest in, and a lien on, substantially all of the Debtors. Upon an Event of Default under the 2024 First Note, each Investor may exercise its rights to the collateral pursuant to the terms of the Security Agreement.

IP Security Agreement

In connection with the issuance of the 2024 First Notes, the Company also entered into an Intellectual Property Security Agreement with the Collateral Agent (as defined therein) on behalf of the Investors on the Initial Closing Date (the “IP Security Agreement”), pursuant to which the Company and each of its subsidiaries (together with any persons who execute a joinder to the Security Agreement, the “IP Debtors”) provided as collateral to the investors a security interest in, and a lien on, substantially all of the IP Debtors. Upon an Event of Default under the 2024 First Notes, each Investor may exercise its rights to the collateral pursuant to the terms of the Security Agreement.

Certain Restrictions on Activities

The SPA contains certain restrictions on the Company’s ability to conduct subsequent sales of its equity securities and certain business activities. In particular, subject to certain customary exemptions, from the Initial Closing Date, until 30 days after the Resale Registration Statement goes effective, the Company shall not file any registration statement with respect to the Company’s Common Stock.

The issuance and sale of the 2024 First Notes have not been, and will not upon issuance be, registered under the Securities Act, and the 2024 First Notes may not be offered or sold in the United States absent registration under or exemption from the Securities Act and any applicable state securities laws. The Securities will be issued and sold in reliance upon an exemption from registration afforded by Section 4(a)(2) of the Securities Act and Rule 506(b) promulgated under Securities Act based on the following facts: each of the Investors has represented that it is an accredited investor as defined in Rule 501 promulgated under the Securities Act; that it is acquiring the Securities for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof in violation of applicable securities; the Company used no advertising or general solicitation in connection with the issuance and sale of the 2024 First Notes to the Investors; and the Securities will be issued as restricted securities. This Current Report on Form 8-K is not and shall not be deemed to be an offer to sell or the solicitation of an offer to buy the 2024 First Notes.
